  • Patent number: 5884757
    Abstract: A beverage-containing article carrier includes a supporting frame and a release strip member. The supporting frame member contains a first set of openings having a diameter which is larger than the necked portion of bottles retained in the carrier. The release strip is releasable relative to the supporting frame and covers a portion of the first openings. The release strip further includes a plurality of arc-like recess portions, which combines to form with the uncovered portions of the first openings, a set of second openings having a diameter sized to retain the necked portion of a beverage-containing article, such as a bottle or can. Preferably, the second openings each include a set of retaining tabs, whereby removal of the release strip causes at least one of the tabs to be removed, allowing a predetermined number of articles to drop through the first openings.

  • Patent number: 5028188
    Abstract: An expandable mine bolt assembly having a shell and wedge unit threaded upon the shank of an elongated bolt. The shell contains at least one or more leaf sections. The arms of a U-shaped metal strap are joined to the shell and the strap is arranged to pass over the wedge and the distal end of the bolt. At least one arm of the strap is provided with a wrapped section containing folded legs. The distal end of the bolt applies pressure against the strap as the bolt is threaded through the wedge which, in turn, causes the legs of the wrapped section to unfold into holding contact against the wall of a receiving hole thereby preventing the assembly from spinning in the hole as the shell is being expanded by the wedge.
